When Jeff Fisher was fired by the Rams in December, the NFL world let out a crude-but-unanimous cheer. Many had viewed the head coach's firing as an overdue inevitability, Sporting News included.

But a video shared on social media Thursday pulled back the curtain on the collateral damage caused by head coach firings annually in the NFL. Assistant coaches, many of whom are not at fault for whatever organizational shortcomings lead to drastic changes, are affected and often let go, as well.

The NFL's Twitter account shared a clip from "All or Nothing: A Season with the Los Angeles Rams" that reveals the moment Fisher informed his staff of his own fate. Their reactions imply that they, too, immediately realized theirs.

"Unfortunately, I won't be there this weekend... I was just fired." - Jeff Fisher

"Sorry if I let you guys down," Fisher told his assistants. "You guys didn't let me down. You busted your ass every single day for me. I will do whatever I can (for) every single one of you. I will be there for you, when the season's over, recommend you, call to the end of the night to help you guys find work."

Of those who were on the Rams' 2016 coaching staff, only special teams coordinator John Fassel, running backs coach Skip Peete and assistant offensive line coach Andy Dickerson were retained on new head coach Sean McVay's 24-man staff for the 2017 season. Fassel served as interim head coach for the last three games last season after Fisher was fired.
